[−][src]Struct tower_web::extract::Immediate
Implements ExtractFuture such that the result is immediately available.
This type is useful when implementing Extract for types that do not
require any asynchronous processing. For example, extracting an HTTP header
value from an HTTP request can complete immediately as all the information
is present.
Methods
impl<T> Immediate<T>[src]
impl<T> Immediate<T>pub fn result(result: Result<T, Error>) -> Immediate<T>[src]
pub fn result(result: Result<T, Error>) -> Immediate<T>Create a new Immediate instance from a Result value.
When polling the returned Immediate instance, it will yield result.
pub fn ok(value: T) -> Immediate<T>[src]
pub fn ok(value: T) -> Immediate<T>Create a new Immediate instance that is in the success state.
When polling the returned Immediate instance, it will yield value.
pub fn err(error: Error) -> Immediate<T>[src]
pub fn err(error: Error) -> Immediate<T>Create a new Immediate instance that is in the error state.
When polling the returned Immediate instance, it will yield error.

The argument extracted from the request.
fn poll(&mut self) -> Poll<(), Error>[src]
fn poll(&mut self) -> Poll<(), Error>Returns Ok(Ready(())) when extract() can be called. If NotReady is returned, the current task is registered for wakeup. Read more
